Checks for duplicated names within a UKB dataset
ukb_df_duplicated_name(data)A UKB dataset created with ukb_df.
Returns a named list of numeric vectors, one for each duplicated variable name. The numeric vectors contain the column indices of duplicates.
Duplicates *within* a UKB dataset are unlikely to occur, however, ukb_df creates variable names by combining a snake_case descriptor with the variable's **index** and **array**. If an index_array combination is incorrectly repeated in the original UKB data, this will result in a duplicated variable name. .
